Calculate U.S. duties, buffer them into your product pricing, and ship with Royal Mail.
Royal Mail has partnered with Zonos to help you calculate duties upfront and price your products correctly for Delivered Duty Paid (DDP) shipping. You calculate the duties using Zonos tools, then Royal Mail handles the shipping and duty remittance.
U.S. import requirements reach further into product-level data than they used to. Steel and aluminum items need a declared metal origin or the parcel is charged a punitive default Section 232 rate, and starting January 20, 2027, products regulated by U.S. agencies must have that agency's data filed electronically with the customs entry. At the same time, postal shipments under $2,500 USD can have free trade agreements applied to reduce duty — provided the supporting documentation travels with the shipment.
A Zonos Verified Account is where you hold that data. You sync or upload your catalogue once, Zonos flags the items that need more detail before they can ship to the U.S., and you answer the questions or attach the documents. The details are stored against the product, so you provide them once and they apply to everything you send afterward.
This is separate from how your duties are handled. Duty prepayment works as described above, and a Verified Account is not used for duty billing.
